SPECIFICATION forming part of Letters Patent N 0. 738,679, dated September 8, 1903. Application filed May 16, 1903. Serial No. 157,451. (No model.)

To all whom it may cancer-n.-

Be it known that we, HART HATCH and JOHN O. CRIoKs, citizens of the United States, re-' siding at Tarentum, in the county of Allegheny and State of Pennsylvania, have invented newand useful Improvements in Bot tle-Closures, of which the following is a specification.

tection.

The invention consists, essentially, of a bttle having primary and secondary necks separated by a frangible groove, the secondary neck having a stopper permanently held therein and provided with ball-locking devices and the primary neck having a removwhich willbe more fully herein after described able cork-stopper which is accessible only after the secondary neck is broken off when the bottle is originally opened.

The invention also consists in the construction and arrangement of the several parts,

and claimed;

in the drawings, Figure 1 is a transverse vertical'section through a bottle-neck, showing the features .of the invention and illustrating the position of both closures before the secondary neck is removed. Fig. 2 is a transverse vertical section through the bottle-neck as it appears before the stoppers are inserted therein. Fig. 3 isa perspective view of the stopper for the secondary neck.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates the primary neck, which extends directly up from the body of the bottle and has thereon a secondary neck 2, separable therefrom throughthe medium of inner and outer grooves 3 and 4, separated by a frangible web 5. The upper secondary neck 2 has a central bore 6 equal in diameter to the bore 7, extending through the main portion of the primary neck 1, and the bore 6 terminates at an enlarged bore 8, which forms a seat and provides a circumferential sh0nlder 9. The. lower terminal of the bore 8 terminates at the inner groove 4, and at the upper portion of the primary neck 1 a stopperseat 10 is formed and converges in a downward direction to a circumferential shoulder 11. Acork-stopper 12 is fitted in the seat 10, and theupper end thereof is formed with a concave depression 13. The stopper 12 is inserted in the seat 10 after the bottle has been filled, and the diameter of the said stopper is greater than that of the bore 6, so that it is materially compressed when forced into the neck 2 and expands after reaching the bore 8 and still further after being firmly pressed into itsseat 10, the bore 8 beingslightly less in diameter than the maximum diameter of said seat. After the stopper 12 is fully pushed downward into its seat melted paraffin or analogous material is poured into the neck 2 and deposits on the stopper 12. While the paraffin is still in fluid condition a glass or other suitable non-pressible stopper 14 is inserted in the secondary neck 2, the upper and lower ends of said stopper 14 being convex in contour. The stopper 14 is formed with diametrically-opposed recesses 15, communicating with depressions 16 below the same of materiallyless depth. In the recesses rubber plugs 17 are mounted and are sufficiently elastic to be compressed by locking devices which are primarily held in the recesses 15 against the outer terminals of theplugs when the stopper 14 is inserted in theneck 2. These locking devices consist of steel balls 18, which are applied to the outer ends of the rubber plugs 17 and pressed into the recesses 15 and held in thelatter until the stopper 14 is pressed down far enough to permit the plugs to force the balls outwardly under the shoulder 9.

This downward movement of the stopper 14 to dispose the balls 18 under the shoulder 9 is permitted in view of the elastic or yielding nature of the stopper 12, and, after the balls become seated under the shoulder thestopi-h per 14 rises to a normal position orso that the plugs Will'be above the balls, and the latter will be retained between the shoulder 9 and the depressions 16, and hence it will be impossible to withdraw the stopper 14 from the neck 2. As before stated, the stopper 14 is forced downwardly against the melted paraffin first disposed on the stopper 12, and as IOC the lower extremity of the stopper 14: takes up the space occupied by the paraffin the latter is forced upwardly into the annular chamber around the lower extremity of the stopper 14 and produced by the difference in diameter between the stopper and the bore 8,and hence the said paraffin fully surrounds the balls 18 and enters the depressions 16 to obstruct the use of acids in attempting to open the bottleneck without pursuing the regular method, A thin layer of paraffin will be pressed between the lower end of the stopper 14: and the upper end of the stopper 12, and in addition to the locking effect of the balls 18 the plugs 17 will exert a binding pressure on the wall of the bore 6. After the bottle has been sealed in the manner set forth and it is desired to regularly use the contents the secondary neck is struck a light blow and separated by breaking the web 5. This will expose the stopper 12, and the latter may easily be withdrawn to dispense the contents of the bottle. The stopper 12 also serves to prevent the entrance of small particles of glass into the contents of the bottle at the time the secondary neck is separated from" the primary neck. The special features which are considered essential or advantageous in the present construction are the cheapness of manufacture and effectiveness in preventing entrance into the bottle without first removing the secondary neck.

Changes in the proportions, dimensions, and minor details of construction may be resorted to without departing from the spirit of the invention.

Having thus fully described the invention, what is claimed as new is- 1. A bottle-closure of the .class set forth, comprising a primary and secondary neck,

having a breaking-groove between them, the secondary. neck being formed with a lower bore of increased diameter to provide an upper circumferential shoulder, a stopper mov ably inserted in the upper extremity of the primary neck, a stopper inserted in the secondary neck and having diametrically-opposed recesses with yielding plugs therein, the stopper in the secondary neck being the same in diameter as the minimum diameter of the bore of said neck, and locking devices loosely held against the plugs when the stopper in the secondary neck is inserted, and sprung under the shoulder in said neck.

2. A bottle-closure of the class set forth, comprising primary and secondary necks connected by breakable means and having bores therethrough, the said bore of the secondary neck being increased in diameter at its lower portion to form a circumferential shoulder, a stopper inserted in the upper portion of the primary neck, paraffin introduced over the said stopper, a stopper in the secondary neck of less diameter than the lower portion of the bore in the latter and when seated, adapted to force the paraffin up into the space between thelower part of the stopper in the secondary neck and the wall of the lower increased bore, and lockingballs interposed between the stopper in the secondary neck and the said circumferential shoulder.

In testimony whereof we affix our signatures in presence of two witnesses.
